| Abstract: | Objective evaluation of regional crustal stability in a city is of vital significance to safety and sustainable development of the sity.Geological survey in Harbin was conducted to examine the the Moho depth,geophysical field,igneous rocks and historical earthquake records,and in Harbin the magnetotelluric sounding,drilling and mercury vapor survey were carried out.The research results show that the crust structure in Harbin is continuous,complete and stable,and earthquake activities of more than moderate intensity will not occur. |
